SPEAKER PLACEMENT

Polk Audio LCFX Surround Loudspeakers give you nearly endless placement options. But remember that where you place your surround speakers requires some careful thought, as installation requires that you cut a hole in your wall or ceiling

Left/Right Orientation: LCFX Surround Speakers have a left/right orientation, and each speaker is clearly marked on its baffle for installation on either the right or left. Right and left are defined from your listening area as you face your system’s center channel.

Directing the Driver (LC80FX)

The fixed 15° angled driver in the LC80FX allows you to direct the midrange towards your listening area when used for front stage (left-center-right). When used as rear surrounds or as 6.1 or 7.1 back speakers, direct the driver towards the listening area for a more direct sound field or toward a wall for a more diffuse sound field

IMAGING

Solid/Diffuse Switch (LC65FX/LC80FX)

LCFX Surround Loudspeakers offer switchable “Solid” and “Diffuse” imaging patterns to create the surround effect you desire.

A “Diffuse” image is defined as one which creates a “cloud” of sound; think of the effect as ambient sounds which fill the environment all around you.

A “Solid” image is one which creates a more pin-point sound; sound is more directional and localized. Ultimately you are the best judge of what kind of surround imaging you prefer.

The schematic drawing of the room represents an ideal placement for all speakers in either a 6.1 or 7.1 speaker system.

In-wall and in-ceiling loudspeakers excel when placed more than 2' (60cm) from side walls. If position limitations demand that in-wall loudspeakers be installed closer than 2'(60cm) from side walls, the proximity of the surface can result in a response “bump” between 50 and 200Hz. This can cause in-wall speakers to sound “boomy.” The Wall Distance Switch flattens response and tunes out “boominess” without sacrificing deep bass response, for more lifelike sound.

If placement is closer than 2' to a wall: Engage the Wall Distance Switch (“Wall Dist.”) to match the <2' setting. Recommended speaker distance from side walls is 2 feet (60cm).
